if u have declared a attribute in ur component controller , thn u can acess it in ur view using

wd_comp_controller->gv_variable

where name of ur context attribute in comp controller is gv_variable

u cn do it thru code wizard as well

Well, you can use the wizard. Just call any method from the component controller. The wizard will create you the code including the line how you will get a reference to the component controller, which is the point here.

After you have the reference to the component controller, let's say lo_component_controller, you can access its attributes like this:

lo_component_controller->your_attribute

Then of course delete the unnecessary lines of code.

HI,

How to declare this WD_COMP_CONTROLLER?

Hi

WD_COMP_CONTROLLER is reference variable to component controller

By default it was available in view attributes tab.

Older Support Package levels didn't have the built-in attribute for WD_COMP_CONTROLLER. You had to use the following code to access the component controller:

DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).

Actually some of the code wizards still generate this even now that we have WD_COMP_CONTROLLER built in.
